score could not save to the cloud

I updated musecore to the second latest version (4.4.1) , however ignored the latest update (4.4.2) because It was tedious. Afterwards my score would not save to cloud, and there was a notification that stated that:

"Musescore.com returned an error code: 401 authorisation required"

It said to try again later, which I waited for a whole day for, or to get help from here.
